BED MOUNTING.

Application filed May 27, 1927. Serial No. 194,751.

There is a popular demand for beds so mounted and constructed that theymay be housed in an upright position in a closet or other smallspace,'when not in use, and be swung clear of the'closet when broughtinto a horizontal. service position. The object of the present inventionis to produce a simple and novel mounting for a bed structure, wherebythe latter may be swung between an upright position and a horizontalposition, in

either direction, with little effort, the bed travelling horizontally aconsiderable distance in shifting it from one position to the other,whereby the bed may be stored in the closet or the like in an uprightposition when not in use and be swung completely out of the closet whenhorizontal.

If the structure as a whole is mounted on casters, it becomes aroll-away bed and therefore, viewed in one of its aspects, the inventionmay be said to have for its object to produce a simple and novelmounting for a bed of the roll-away type.

The various features of no elty whereby my invention is characterizedwill hereinafter be pointed out with particularity in the claim; but,for a full understanding of my invention and of its objects andadvantages, reference may be had to the following detailed descriptiontaken in connection with the accompanying drawing, wherein: I

Figure 1 is a side View of my improved bed occupying its horizontalposition; Fig. 2 is a view similar to Fig. 1, the bed being in avertical position; Fig. 3 is a plan view, on a larger scale, of afragment of the struc ture, and Fig. 4 is a section taken approximatelyon line 44 of Fig. 3.

Referring to the drawing, 1 represents one of the side rails and 2 and 3portions of the head and foot, respectively, of a bed of any usual orsuitable construction. In the arrangement shown, the head member of thebed has a folding section 4 at the top while the foot member has abottom swinging or folding section 5, this construction be ng similar tothat disclosed in the application of Charles L. MacIntosh filed March 2,1927, Serial No. 171,933. Furthermore, the swinging sections 4 and 5 maybe moved automatically by means of devices such as employed in theMacIntosh bed, such devlces being actuated by one of the swingingelem'ents, conveniently the bar 12 to be hereinafter described. Abed-supporting arm 6 is pivoted at its lower end to the front end of abase member 7 and has at its upper end a roller 8 rlding in a slot 9extending lengthwise in the adjacent side frame member 1.

If this frame member consists of an angle iron, the slot may be formedby securing underneath the horizontal flange of the angle iron a bar 10in the form of a flattened U.-

The head end of the bed is connected to an upright part or post 11 ofthe base member/(by a bar 1 2 in the form ofa flattened V, theconnection between this bar and the part 11 being at a considerableelevation from the floor. Between the member 11 and the arm 6 is aflexible connection, consisting convenientlyof two links, 13 and 14,hinged. together and pivoted, one to the member 11 and the other to thearm 6. At the joint between the links 13 and 14 is a roller 15,preferably having a peripheral groove, disposed in the plane of swingingmovements of the bar 12. A strong spring 16 extends diagonallydownwardly and away from the bed frame to the base member.

When the bed is swung into its horizontal position as shown in Fig. 1,it is supported at the head end from the arm 6 and the bar 12, thelatter resting on the roller 15. The downward pressure on the bed end ofthe bar tends to cause the bar to force the roller 15 down and thusswing the upper end of the arm 6 toward the left. A state of equilibriumis reached when the roller on the arm 6 arrives at the left hand end ofthe slot within which it plays. The spring is now under considerabletension. When the bed is to be swung into its upright post tion, thefoot end is lifted, thus swinging the bed as a whole about the roller 8as a pivot, the head end moving downward. This movement is aided by thespring 16. However, any downward movement of the head end of the bedresults in swinging the bar 12 down and pressing down the roller 15, sothat the arm 6 must swing toward the left. As the upward movement of thefoot end of the bed continues, the arm 6 is brought into an uprightposition, with the roller 8 in the opposite end of the slot 9 from thatin which it lies in Fig. 1, one arm of the bar 12 assuming anapproximate- 1y vertical position, and the other arm which is the onepivoted to the bed, assuming an approximately horizontal positiondirectly above the base.

The upper end of the arm 6 is bent back with respect to the remainder ofthe arm,

as indicated at 17, so that when the bed is in an upright position, themain portion of the arm 6 stands up outwardly from or in front of thebed and the weight of the bed is therefore exerted in a direction tohold the bed upright.

There will usually of course be two of the supporting mechanisms, suchas I have described, one at each side of the bed; or, the base may be aswide as the bed and be provided at each end with a set of arms and barsand links. The number of such mech anisms is not important, however,since the feature of my invention has to do with a supporting structuremade up of a few simple elements and a spring, that will permit a bed tobe swung up and down, while countor-balanced, and to be moved bodilythrough a considerable distance in the direction of its length whilepassing between its upright and its horizontal positions.

While I have illustrated and described with particularity only a singlepreferred form of my invention, I do not desire to be limited to theexact structural details thus illustrated and described; but intend tocover all forms and arrangements which come within the definitions of myinvention constituting the appended claim.

I claim: t

In combination, a base having at the rear end an upright post, a bedadapted to be positioned in front of the base when horizontal, a barpivotally connected at its ends to the post and the adjacent end of thebed, an arm pivoted at its lower end to the base and extending upwardlyand forwardly to the bed when the latter is horizontal, meansconnectingthe upper end of said arm to the bed for sliding movements fora limited distance in the direction of the length of the bed, a flexibleconnection between the post and an intermediate point on said arm, andcooperating elements on said bar and said flexible connection to causethe latter to be flexed in a direction to swing said arm toward anupright position when the remote end of the bed is lifted.

In testimony whereof, I sign this specification.

JOHN BENGTSON.
